I took it with me to fieldwork at the Bahamas, was really hard on it for two weeks, crawling under bushes, climbing rocks, strolling through the sea, sitting out in the rain, and I couldn't have chosen a better bag to take. Was always there, a lot more comfy, than a backpack, but almost as much space inside, kept things dry, additional gears and gadgets can be attached to strap, all together: won't take anything else with me ever again.
